DIY vs Licensed Electrician: What You Can Legally Do Yourself in QLD
Everyone has stood in front of a dead power point with a screwdriver in hand, thinking: how hard can this actually be? The wiring looks simple. There’s a video for it. The part costs eight dollars.
The honest answer has nothing to do with whether you could follow the steps. It’s that Queensland law draws the line a long way back from where most people expect — further back than “don’t touch live wires”, and further back than most DIY guides suggest. This guide sets out where the line actually sits in the legislation, which tasks fall on each side of it, and which of the widely-believed “it’s probably fine” jobs are illegal.
What the law counts as “electrical work”
Section 18 of the Electrical Safety Act 2002 defines electrical work in two limbs: connecting supply wiring to electrical equipment or disconnecting it, and “manufacturing, constructing, installing, removing, adding, testing, replacing, repairing, altering or maintaining electrical equipment or an electrical installation.”
That sentence is doing more work than it looks like. It doesn’t just cover running new cable through a wall. It covers replacing a power point. It covers swapping a light switch. Because it names testing, it also covers testing and tagging portable equipment — which is why Queensland handles test and tag differently from most states.
If a task falls inside that definition, only a licensed electrical contractor — or one of their licensed electrical workers — can legally perform it. There is no “it’s my own house” exemption and no size threshold below which it becomes acceptable. A single power point swap and a full switchboard rewire sit on the same side of the line.
What you can legally do yourself
Section 18(2) lists what is not electrical work. The household-relevant exclusions are short, and most of them involve no wiring contact at all:
| Task | Allowed? | Why |
|---|---|---|
| Changing a light bulb, including LED downlight globes | Yes | Named in s18(2)(c) as a replacement that can be safely done without electrical expertise |
| Replacing a fuse | Yes | Also named in s18(2)(c). Worth knowing, because a fuse that keeps blowing is a fault to diagnose, not a part to keep buying |
| Resetting a tripped circuit breaker or safety switch | Yes | Operating an existing device as designed, not altering it |
| Pressing the safety switch test button | Yes | Same — using the device’s built-in function. Do it quarterly |
| Plugging equipment into a power point, or using an approved extension lead or power board as intended | Yes | s18(2)(a) excludes connection made by a flexible cord, plug and socket outlet |
| Replacing a washing machine drive belt, a fridge door seal, or similar non-electrical part | Yes | s18(2)(b) — work on a non-electrical component, where you aren’t exposed to an electrical hazard. The Act uses the drive belt as its own example |
| Mounting a battery-powered smoke alarm | Yes | s18(2)(n) — fixing equipment in place, as long as you’re not making an electrical connection. The alarm still has to meet Queensland’s smoke alarm requirements |
| Cutting the wall opening for an air conditioner, without connecting it | Yes | Carpentry, not electrical work. The connection is a separate job and is not |
| Positioning an electric wall oven into its cavity, without wiring it in | Yes | s18(2)(f) — locating or fixing equipment in place, where it isn’t done as part of connecting it to supply |
Notice the pattern. Every permitted task either involves no contact with fixed wiring, or is using pre-manufactured equipment the way anyone is meant to use it. The moment a task requires opening a fitting, terminating a conductor, or altering a circuit, it crosses the line.
What legally requires a licensed electrician
This is the longer list, and the one most homeowners underestimate:
| Task | Allowed? | Why |
|---|---|---|
| Installing or replacing a power point | No | Direct wiring contact. The Electrical Safety Office names it specifically, and so does the cost of adding one |
| Installing or replacing a light switch | No | Named by the regulator. A switch replacement means disconnecting and reconnecting live conductors |
| Installing a hard-wired light fitting | No | The bulb is yours; the fitting is not. Replacing a batten holder with a new fitting is listed as licensed work |
| Replacing a light fitting with a ceiling fan | No | The regulator names this exact job. The mounting is a second problem again |
| Repairing an electrical appliance internally | No | Repairing electrical equipment is electrical work under s18(1)(b) |
| Connecting an oven, cooktop or hot water system | No | The physical fit can be DIY. The electrical connection cannot |
| Installing a hard-wired smoke alarm | No | Connected to fixed wiring, unlike a battery-only unit |
| Any switchboard work — upgrades, new circuits, RCD or RCBO installation | No | The highest-risk category of electrical work in a house |
| Connecting solar panels, inverters or battery storage | No | High-voltage DC and grid-interactive equipment. Specialist accreditation applies on top of the licence |
| Installing an EV charger | No | Hard-wired, dedicated circuit, network notification. See the EV charger requirements guide — and note you can trickle charge from an existing power point |
| Data, network or telecommunications cabling | No | A separate ACMA cabler registration regime. Different rules, same principle |
| Test and tag of portable appliances for a business | No | s18(1)(b) includes testing electrical equipment, which is why Queensland’s rule differs from other states |
If a task sits in this table, no amount of confidence, prior experience or careful research changes its legal status. It needs a licensed electrician.
The grey areas everyone gets wrong
These are the tasks that catch out careful, safety-conscious people, because the legal line sits in a slightly different place than common sense suggests:
| Task | What people assume | What’s actually true |
|---|---|---|
| Replacing the plug on a damaged extension lead | “It’s just a plug, anyone can do this” | Illegal. The Electrical Safety Office lists constructing an extension lead and replacing a plug on the end of one as licensed electrical work |
| Low-voltage garden lighting | “It’s low voltage, so it must be fine” | Depends A plug-in transformer kit that plugs into an existing power point is generally fine. A transformer hard-wired at the switchboard is licensed-only |
| Fitting an electric wall oven | “I installed the oven myself” | Partly Sliding it in and securing it is fine under s18(2)(f). Connecting it is not, and handling the wiring while fitting it puts you on the wrong side of both the law and the risk |
| Cutting the wall opening for a split system | “I did most of the aircon install myself” | Partly The cut-out is fine for a competent DIYer. Running the circuit and connecting the unit is licensed work, and the refrigerant side needs its own licensing again |
| “I’ll get it certified afterwards” | “An electrician can just sign off what I’ve already done” | Not possible. A compliance certificate covers work the licensed contractor performed and tested. It isn’t a stamp for existing unlicensed work |
The pattern across every grey area: mechanical and carpentry-adjacent tasks are usually fine. Anything involving an electrical connection — even the last five centimetres of it — isn’t.
Why the law draws the line here
The strictness isn’t bureaucratic overreach. Three specific risks drive where the line sits.
- Shock and electrocution. Domestic supply in Australia is 230 V nominal — more than enough to kill under the wrong circumstances. Training and test equipment exist because the failure mode of “I got it slightly wrong” is sometimes fatal rather than inconvenient.
- Fire risk you can’t see. A poorly terminated connection can run for months or years before it fails, heating at the joint until insulation degrades and arcing starts inside a wall cavity.
- Compounding risk for the next person. Unlike a wonky shelf, faulty electrical work doesn’t only fail — it can injure the next occupant, tradesperson or family member, who has no idea the work wasn’t done to standard.
What happens if it goes wrong
The Electrical Safety Office publishes the penalties for unlicensed electrical work directly:
Penalties for unlicensed electrical work in QLD
- Up to $40,000 for an individual performing unlicensed electrical work, whether or not anyone was hurt
- Up to $600,000 for an individual, or $3,000,000 for a corporation, plus up to five years’ imprisonment, where the work exposes someone to a risk of death or serious injury
None of this requires anyone to catch you mid-job, and the fine is rarely what people actually meet. The exposure turns up later, through three quieter channels.
- No compliance certificate exists. In Queensland the duty to provide a compliance certificate sits with the licensed contractor, and there is a penalty for failing to provide one. Work nobody licensed performed has no certificate behind it, and it can’t be issued after the fact — a licensed electrician would need to inspect and typically redo the work to certify it.
- Insurance, but not the way people think. “Unlicensed work voids your policy” is the common claim and it’s overstated. Most home policies contain no clause about unlicensed electrical work at all; the real exposure is a claim denial under general exclusions like faulty workmanship or unlawful acts, and it turns on whether the work caused the loss you’re claiming. We’ve set out how that actually plays out in does DIY electrical work void home insurance.
- Resale and settlement. Undocumented electrical work is a common finding in a pre-purchase electrical inspection. At best it triggers a negotiation and a compliance-repair cost taken off the price. At worst it delays a settlement.
Appliance warranty is the fourth, quieter one. Manufacturers of ovens, EV chargers and solar inverters generally require licensed installation as a condition of cover, so DIY-connected equipment that fails is often outside warranty regardless of what caused the fault.
How to check your electrician is actually licensed
Before any electrical work — DIY temptation aside — confirm that whoever you’re hiring holds a current licence. Queensland makes this free and instant.
- Ask for the licence number. A licensed contractor will give it to you without hesitation.
- Search it on the public register. The Electrical Safety Office runs an electrical licence search that shows current status.
- Check it’s a contractor licence, not a restricted one. Restricted licence holders can perform a narrow, defined scope of work — not run an independent job.
- Ask for the certificate at completion. Keep it. You’ll want it at resale, at insurance renewal, and at any future fault.
Our licence — QLD Electrical Contractor Licence 1511406 — is on that same public register, checkable by anyone, any time.
Commercial, strata and body corporate: same principle, heavier duty
For business owners, property managers and body corporate committees the DIY question rarely arrives in the same form, but the obligation is heavier rather than lighter. As the person conducting a business or undertaking, a business owner carries an active duty to ensure electrical work on the premises is performed by licensed contractors and properly certified.
A well-meaning maintenance person having a go at a power point in a commercial kitchen or a body corporate common area carries the same illegality as a homeowner, with considerably more liability attached. Where the boundary sits between the body corporate and the lot owner is a separate question, covered in body corporate vs unit owner electrical responsibilities, and fit-out work has its own rules again.
Gold Coast: where this comes up most
The jobs we’re most often called to unwind are in older housing stock where someone competent had a go a decade ago — beachside cottages and post-war brick homes through Palm Beach, Currumbin and Burleigh Heads, and walk-up unit blocks through Labrador and Surfers Paradise where one lot owner’s weekend job becomes the body corporate’s problem.
Coastal air makes the timing worse rather than the rule different. Salt-laden humidity accelerates corrosion at terminations, so a marginal DIY connection near the beach tends to fail sooner than the same connection inland. If something on your place was done by someone unknown, that’s worth an inspection rather than a wait.
The quick test: is this job DIY-legal?
When you’re standing in front of a job and genuinely unsure, ask three questions in order.
- Does it involve connecting or disconnecting a conductor? If yes, it’s licensed-only. That rules out almost everything except bulbs, fuses and plugging things in.
- Is it on the short list of exclusions? Bulbs, fuses, breaker and safety switch resets, plug-and-socket use, non-electrical parts, mounting without connecting. If it isn’t there, assume it needs a licence.
- Would getting it wrong put someone at risk of shock, fire, or a fault that only shows up later? For electrical work the honest answer is almost always yes — which is the law’s reasoning for where the task sits.
Still unsure after those three? The answer defaults to calling a licensed electrician. That’s not overcaution; it’s how the Act is structured.
Frequently asked questions
Can I replace a power point myself if I turn off the switchboard first?
No. Isolating the circuit doesn’t change the legal status of the work. Installing or replacing a power point is electrical work under section 18 of the Electrical Safety Act whether it’s done live or de-energised. Turning the power off is a real safety improvement, but it doesn’t make the task legal for an unlicensed person.
What’s the difference between a restricted licence and an electrical contractor licence?
A restricted electrical work licence permits a narrow scope of specific tasks, often under defined conditions. It isn’t a general licence to perform electrical work independently. An electrical contractor licence, such as QLD Licence 1511406, permits the holder to run and take responsibility for electrical work as a business. For general residential or commercial work, confirm you’re dealing with a contractor licence.
Is it really illegal to replace the plug on my own extension cord?
Yes. Queensland’s Electrical Safety Office lists both constructing an extension lead and replacing the plug on the end of one as work requiring a licensed electrician. It feels like one of the simplest jobs in the house, which is exactly why the regulator names it directly.
Can an electrician certify electrical work I’ve already done myself?
No. A compliance certificate covers work the licensed contractor performed and tested, not an inspection stamped onto existing unlicensed work. In practice the work usually needs to be properly redone by a licensed contractor before it can be certified.
Does unlicensed electrical work void my home insurance?
Not in the way the claim is usually made. Most home policies contain no clause about unlicensed electrical work, and policies are rarely voided outright. The real risk is a claim being denied under a general exclusion such as faulty workmanship or an unlawful act, and that turns on whether the work caused the loss you’re claiming.
Can I install my own solar panels or EV charger to save money?
No. Both are hard-wired installations requiring a licensed electrical contractor, and in most cases additional specialist accreditation. EV chargers above certain thresholds also require notification to the network operator before installation. Trickle charging an EV from an existing power point is a different question and is generally permitted.
What should I do if I suspect earlier work on my property was unlicensed?
Have a licensed electrician inspect it. If it’s non-compliant it typically needs to be brought up to standard and certified before it can be considered safe or insurable. This is common enough in older Gold Coast homes that it’s worth raising directly when you book any switchboard or wiring inspection.
